Application and odtbe 4', 1923.. serial No; 666,635;

This invention relates to spindle picking of the type usually found on the drop box ends of fancy looms and the generalobject ofv the invention is to provide an improved mounting for the picker spindle usually found on this type. of loom.

Looms of the type referred to employ several shuttles mounted for vertical movement on the lay and in order to propel the various shuttles there is usually provided a picker one end of which ext-ends behind the active shuttle and the other endof which is elon gated and provided with a bore by means of which it is mounted on the picking spindle. The picker stick acts on the picker at some point between the boxes and the spindle.

ln such a construction the picking spindle is subjected to considerable longitudinal strain and the usual method of mounting the spindle. has been to support the inner end on some part of the lay end while the outer end is received bv a support bolted or otherwise secured to the lay. A set screw carried by the support secures the outer end of the spindle so that the latter is held in fixed position with respect to the lay. However, the jar incident to the normal operation of the. loom is such that the set screw is likely to wear loose and to prevent acci dental removal of the spindle from the loom there is usually provided an auxiliary retainer to engage the outer end of the spindle when the latter is loose.

The general object of my invention is to provide a single holding means associated with the support by means of which the spin-dle will not only be held ri gi dly in place with respect to the lay but should the spindle become loose this same means will serve to prevent accidental removal thereof from the loom.

Vith this general object in view and others which will appear as the description proceeds the invention resides in the combination and arrangement of parts hereinafter described and pointed out in the claim. y

In the drawings wherein a preferred form of the invention is shown Fig. 1 is a top plan view of a lay having the invention applied thereto= Fig. 2 is an enlarged rear elevation of the Vthe spindle 17.

to the lay end by means of bolt 19. The

support 18 abuts two sides of the usual lay end flange andthe single bolt 19`is sufficient to hold it from relative motion with respect lto the lay.

A picker 20 is mounted to slide on spindle 17 and has the inner end 21 thereof in hori- Vzontal alignment with the shuttle opposite the shuttle race.

The matter thus far described is of the usual construction and it is to be understood that the form of support 18 may vary with different types of looms.

My improvements are concerned with the method of supporting the outer end of the picking spindle and it will be seen by re ferring to Figs. 2 and 3 that support 18 is provided with a clear hole 22 through which the picking spindle 17 passes. Aligning; with the opening 22 is a threaded bore 23 which receives a screw 24 so arranged as to have the inner end thereof in contact with A lock nut 25 is preferably employed to hold the screw 211 in adjusted position vand if desired this nut may be provided with a cap 26 to cover the outer end of screw 24 and serve as a shield therefor.

lVhen applying my invention to a loom the screw 24 is removed from the bore 23 and the spindle V17 inserted through the aligning openings in the support 18, the spindle being` moved until the inner end thereof is supported Vin lug` 1G. The screw 24 is then inserted in the bore 23 and set up tightly against the spindle after which the lock nut is applied.

It will beobserved that it isV necessary to have the bore 23 of a diameter at least equal to the diameter of the spindle in order that the latter may pass through the support 18.

It will alsorheohserved that the singlescrew 24 serves not only to hold the spindle v17- pens that support 18 works loose with rO-f spect to the lay ond under former construction where this support was held tightly to the spindle both the support and. spindle were subject to inward mot-ion :it the time of picking-hut with the present construction the spindle may move'insvardly with respect to the support 18 Without moving the latter inasmuch as the spindle moves freely in openingl 22.

n Having described one form of my invention it will he apparent that changes and modifications may he made hythose skilled in the art and I do not vWish to be limited to the particular structure set forth, but what I do claim" is n In a mounting vfor a picker spindle for a loom having a ley, the picker spindle having the inner end supported on the lay, a support for the outer end of the spindle mountthe support to restrain longitudinal movement or" the spindle, and means to lock said sere7 in holding position with respect t0 the spindle and support.

In testimony whereof I have hereunto aiixed my signature.

ARTHUR LANCIAULT.
